This drama is really testing you how to read subtitles super fast. Very long, intense dialogues and indeed WeAreAllTryingHere to grasp & read them as fast as the characters are speaking.
Episode 1 missed the hook. Too many characters & less of substance. It picks up with episode 2. Giving another episode a chance for sure. It's a glossy Sageuk with a touch of marriage of convenience.
Ah!!! Hitting all the right notes.

WHAT DID HE KNOW THAT WE DON'T?
